Errors when debugging a plugin

Hi,
It’s been a while since I updated m plugin adn when I try to debug it now, after updating PS and the developer tool I see this error when I click the ‘index.html’:
Error while parsing request of ‘Page.getResourceContent’
I’m not sure about the “no domain” as well.
I use win10, latest update and the plugin is working as expected in PS.

I had no such problems before.
I attached a snapshot of this:

Thanks

I see that occasionally. Hitting F8 will move past it. I’ve always assumed it’s just a timing issue in UDT.

Let me know if you find it’s actually serious!

What should F8 do?
I tried it and I still get this error.
I never had that in the past.

Sorry, if F8 doesn’t kick it into life then I don’t know what your next step is.
